Seconded. I'm selling some stuff on Craigslist right now, and almost every question I get is stuff answered in the ad. I almost want to tell these people "No, you may not have this item. You are too stupid to function."
"Where are you located/How close are you to [town]?" - I put the town/zip in the ad. You don't know how a map works?
"Will it fit in my [model car]?"- I've never owned that car, so how the fuck should I know? I put the dimensions IN the ad. A ruler or tape measure is too complex for you??
...sorry, didn't mean to derail, but gahd, this has been bugging me lately.
